Portulaca plant named ‘SAKPOR001’

ABSTRACT

A  Portulaca  plant particularly distinguished by having a rose flower color, flower blooming period from spring to fall and vigorous, semi-mounding and upright plant growth habit, is disclosed.

Genus and species: Portulaca oleracea.

Variety denomination: ‘SAKPOR001’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Portulaca plant, botanically known as Portulaca oleracea, and referred to by the variety name ‘SAKPOR001’. Portulaca line ‘SAKPOR001’ originated from a hybridization in Kakegawa, Japan in 2006 between the female Portulaca line ‘Mo04-20B-V1’, an unpatented proprietary Portulaca breeding line having a rose flower color and bushy growth habit and the male Portulaca line ‘BB03-36A-2-V4’, an unpatented proprietary Portulaca breeding line with a rose flower color and bushy growth habit.

In August 2006, the female parent line ‘Mo04-20B-V1’ and male parent line ‘BB03-36A-2-V4’ were crossed and some F₁ seeds were obtained. In May 2007, the F₁ seed was sown in the greenhouse, cultivated and plant lines were produced with red and rose colored flowers with a bushy plant habit. The plants were evaluated and plant line ‘K2008-158’ was selected for its rose flower color, flower blooming period from spring to fall and vigorous plant growth habit. In May 2008, line ‘K2008-158’ was vegetatively propagated, cultivated and evaluated. In August 2008, line ‘K2008-158’ was confirmed to be fixed and stable. Line ‘K2008-158’ was propagated and cultivated again in May 2009, May 2010 and May 2011 to reconfirm the stability of the line. Line ‘K2008-158’ was subsequently named ‘SAKPOR001’ and its unique characteristics were found to reproduce true to type in successive generations of asexual propagation via vegetative cuttings.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Salinas, Calif.

-   -   1. Rose flower color;     -   2. Flower blooming period from spring to fall; and     -   3. Vigorous, semi-mounding and upright plant growth habit.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘SAKPOR001’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected on twelve-month-old plants grown under greenhouse conditions in Salinas, Calif. in the fall of 2012. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4^(th) edition (2001).

-   Classification:     -   -   Family.—Portulacaceae.         -   Botanical.—Portulaca oleracea.         -   Common.—Purslane.         -   Designation.—‘SAKPOR001’. -   Parentage:     -   -   Female parent.—Proprietary Portulaca line ‘Mo04-20B-V1’             (unpatented).         -   Male parent.—Proprietary Portulaca line ‘BB03-36A-2-V4’             (unpatented). -   Growth:     -   -   Time to produce a rooted cutting.—About 2 weeks.         -   Environmental conditions for plant growth.—The terminal 1.0             to 1.5 inches of an actively growing stem was excised. The             vegetative cuttings were propagated in five to six weeks.             The base of the cuttings were dipped for 1 to 2 seconds in a             1:9 solution of Dip 'N Grow (1 solution:9 water) root             inducing solution immediately prior to sticking into the             cell trays. Cuttings were stuck into plastic cell trays             having 98 cells, and containing a moistened peat moss-based             growing medium. The cuttings were misted with water from             overhead for 10 seconds every 30 minutes until sufficient             roots were formed. Rooted cuttings were transplanted and             grown in 20 cm diameter plastic pots in a glass greenhouse             located in Salinas, Calif. Pots contained a peat moss-based             growing medium. Soluble fertilizer containing 20% nitrogen,             10% phosphorus and 20% potassium was applied once a day or             every other day by overhead irrigation. Pots were             top-dressed with a dry, slow release fertilizer containing             20% nitrogen, 10% phosphorus and 18% potassium. The typical             average air temperature was 24° C. -   Plant description:     -   -   Habit and form.—Vigorous, semi-mounding and upright.         -   Life cycle.—Annual.         -   Height (from soil line to top of foliage).—Approximately 8.0             cm.         -   Spread.—Approximately 30.0 cm.         -   Flowering requirements.—Blooms repeatedly from spring to             fall.         -   Temperature tolerances.—Excellent resistance to rain, heat,             and drought.
